Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D rendering programs struggle to render static or dynamic 2D data, such as images and videos, in real time within a 3D space, limiting the ability to experience a 3D player that can receive and play 2D video streams effectively.
Innovation Solution
A system and method for encoding and decoding 3D data by generating 2D patch data, patch area separation information, and 3D spatial information from 2D data, converting it into 3D data, and encoding it for real-time rendering using existing 3D media processing tools.

1Speed
If existing 3D rendering programs are used to render 2D data, then 3D space placement is achieved, but real-time rendering capability is limited
Solution Approach 1:
The patent introduces an intermediary conversion process that transforms 2D data into a specialized 3D data format with spatial information embedded. This intermediary format acts as a bridge between existing 3D rendering tools and 2D data, enabling real-time rendering without requiring fundamental changes to the rendering engine. The conversion module prepares 2D images with depth and spatial metadata, allowing standard 3D viewers to display them in real-time.
Solution Approach 2:
The patent changes the parameter representation of 2D data by embedding spatial coordinates, depth information, and camera parameters directly into the data structure. By transforming 2D images into 3D data structures with explicit spatial parameters, the system enables real-time rendering while maintaining compatibility with existing 3D rendering pipelines. The parameter transformation allows the rendering system to process 2D data as if it were native 3D data.
2Productivity
If 2D data is converted to 3D data format, then real-time rendering capability is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing pipeline into distinct functional modules: a conversion module that handles 2D to 3D transformation, a spatial information embedding module that adds depth and position data, and a rendering module that processes the converted data. This segmentation allows each module to be optimized independently and simplifies the overall processing complexity by dividing the conversion task into manageable steps that can be processed efficiently in real-time.
Solution Approach 2:
The patent performs preliminary conversion of 2D data into a pre-formatted 3D data structure before the actual rendering process. By preparing the data in advance with embedded spatial information and optimizing the format ahead of time, the system reduces the computational burden during real-time rendering. The preliminary action includes transforming the data format, embedding metadata, and preparing rendering parameters in advance.
